One of the great difficulties of using the command line tools is that it is next to impossible to see a list of more than a few instances and be able to determine which machine is performing which task. Simply providing a 'name' column in the EC2 instances window would be very helpful. Grouping would be nice, too. Being able to rearrange the columns in that view is very important. I can emulate grouping via the security group column, since groups of machines tend to share a security group, but with that column WAY over to the right, I can't ever see it.
